How much hair is cut for a hair drug test? True hair follicle testing requires the hair to be “plucked” rather than cut which can lead to extreme donor discomfort. During a hair drug test collection, the hair is cut as close to the scalp as possible, so only the strands of hair above the scalp is tested and not the actual hair follicle. The hair follicle is actually the pocket, below the scalp, from which the hair strand grows. What is the difference between hair testing and hair follicle testing?Ĭalling a hair test a hair follicle test is a common misnomer. Therefore, a hair analysis of 3.9 centimeters covers a time span of approximately 90 days and detects a pattern of drug use over this time frame.

I thought that it was going to be dead quite and they would be looking for people to cheat the test but it seems like they didn’t give a shit as long as it passed temp.
